Given numbers are 890,794,721,854,669
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 890,794,721,854,669 is 10396130702370.
Find LCM of 890,794,721,854,669 with Prime Factorization
| 2 | 890, 794, 721, 854, 669 |
| 7 | 445, 397, 721, 427, 669 |
| 445, 397, 103, 61, 669 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 445 x 397 x 103 x 61 x 669 = 10396130702370
Therefore, the lowest common multiple of 890,794,721,854,669 is 10396130702370.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
890 x 794 x 721 x 854 x 669 = 291091659666360
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
890 : 1, 2, 5, 10, 89, 178, 445, 890
794 : 1, 2, 397, 794
721 : 1, 7, 103, 721
854 : 1, 2, 7, 14, 61, 122, 427, 854
669 : 1, 3, 223, 669
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,794,721,854,669, is 1.
Now, the common factors can be found like this.
890:2x 5x 89
794:2x 397
721:7x 103
854:2x 7x 61
669:3x 223
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 7 = 28
Therefore, the value for common factors is 28.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 291091659666360/(1x28)
LCM = 291091659666360/28
LCM = 10396130702370
Thus, we can understand that the LCM of 890,794,721,854,669 is 10396130702370.
